SOLUTION:-

At the latest, DDoS attacks occurred progressively innovative and brutal. Recently, In Japan, almost 50,000 video cameras were infected with Linux malware and the Mirai botnet. This amalgamation was utilized to attack different computers & systems all over the world. In the meantime , the Russian Defense Ministry mentioned that a total of 7 DDoS attacks were executed against its website in the duration of the eventual vote on the names of new variety of weapons. That attacks were executed from the Ukraine territory, and as well as in Western Europe & North American countries.

In order to prevent DDoS attacks, the most fundamental method that we can take to make our infrastructure "DDoS obstructive" is to make sure that we must have adequate bandwidth to handle wedge in traffic that may be caused by harmful activity. Thereto, network monitoring software can be helpful in deciding that when a system has become part of a botnet or not. As well as, we must always change the default password for any IoT device installed by us.
